Embodiment Construction

[0031] The following detailed description refers to the accompanying drawings. The same reference numbers in different drawings identify the same or similar elements.

[0032] Embodiments described herein relate to gaze heatmaps. Surveillance cameras stream video of the area of ​​interest to the monitor. Video streaming can have high bandwidth requirements and can consume significant network bandwidth. Additionally, processing video streams may require processor and memory resources. A person viewing the display (referred to herein as an "operator" or "user") may find certain areas of the scene displayed on the display to be of high interest, and may find other areas of the scene to be of low interest. For example, if a camera is monitoring an area with a path and a door, the operator may spend a significant amount of time viewing the door and path, and may spend relatively little time viewing the wall around the door.

[0033] Eye trackers can be used to identify the gaze a...

Abstract

The invention relates to a gaze heat map. A method and a video management system are disclosed. The method may include receiving a video stream from a camera and displaying the video stream on a display. The method may include obtaining, via an eye tracking sensor, gaze information for an operator watching the display. The method may include generating a historical gaze heat map for the video stream for a time period based on the obtained gaze information and determining a low interest area for the video stream based on the generated historical gaze heat map. The method may include instructingthe camera to decrease a bit rate of the video stream in the low interest area.

Description

Background technique [0001] Surveillance equipment such as video cameras can be installed to capture images or video of areas of interest. An operator or group of operators can monitor images or video from the camera on a monitor remote from the camera. The data captured by the camera can be processed and sent to the display via a network connection. For example, images or video can be compressed to reduce the amount of data that must be transmitted over a network. A system can include a large number of cameras that transmit large amounts of data over a network. Large amounts of data can consume network resources. Contents of the invention [0002] According to one aspect, a method performed by a computer device may include: receiving a video stream from a camera; displaying the video stream on a display; obtaining gaze information of an operator watching the display via an eye tracking sensor; generating a time period based on the obtained gaze information A historical ...
